BURNER.

Specification of Letters Patent. Patented Apr. 22, 1913.

Application filed April 8, 1912. Serial No. 689,365.

To all whom it may concern:

Be it known that we, VVARiiI-IUM P. Case STOUT and HERBERT H. )Anonnss, citizens of the United States, ,tesiding at Kinsley,in the county of Edwards and State of Kansas, have invented certainmew and useful Im-' provements in Burners, of which the following is a specification. a a

This invention relates to burners and more especially to devices of that class whereby vapor is generated from oil and mixed with air to form a combustible gas which in burning produces an intense heat,

our primary object beingto produce a simple and eflicient burner whereby consumption of the gas is attained without producing visible smoke or soot.

With this general object in view the 'invention consists in certain novel and peculiar features of construction and combination of parts as hereinafter described. and claimed and in order that it may be fully understood reference is to be had to the accompanying-drawing, in which Figure 1,is aplan viewot a burner embodying our invention. Fig. 2, is a central vertical section of the same. Fig. 3, is a side v1ew of a spreader forming a part oi the burner. v

In "the said drawingyl indicates a base plate which will be circular as shown for heating stoves or furnaces and usually of oblong form ofcook stoves, it being understood that the contour of the base plate will depend 9n the configuration of the combus tion:chamber in which it is located. This plate is provided with an opening 2, and at diametrically opposite sides of said opening with draft openings 3, surrounded by upstanding'circular flanges 4.-.

r 5 1s a draft arch of any suitable height resting upon flanges 4 and bolted as shown at 6 or dtherwise secured to the base plate,

the legs of the arch being adapted to re ceive the arch which enters openings 3. Atits center the arch is provided with a dis char e opening 7 for discharging air downwarcl toward the center of opening 2,

A generator rests upon plate 1 and de pends through the opening thereof and consists of a saucer-shaped base '8 provided centrally with an upstandingcone 9, the saucer having a chamber 10, communicating with the interior of the coue and alsohavingan opening 11 wherein is screwed or otherwise secured an oil supply pipe c12- The upper -wardly,:and the upper extremity of the cone is provided with a series of radial notches 13 constituting gas jet orifices. A device for cooperating with the generator in vaporizing thejoil supplied thereto and for use in spreading the, gas radially as it passes through said orifices, consists of a cylindrical body 14, a tapered lower end 15, a conical head 16, and a plurality of outwardly projecting spacing lugs 17. This device is slipped down into the cone until the head 16 rests upon the cone, the lugs 17 by contact with the wall of the cylindrical portion of" the cone centering the stem l l within the cone, the diameter of thestem being almost equal to the interior diameter of the upper part+of the cone so as to provide a narrow annular. orcircular space up through which the oil will flow and Within which it will be transformed into vapor which will escape through the orifices 13 and at such point through mixture-with the descending air be transformed into a combustible gas. The basepla-te will be'of such size and form as to completely partition off. the combustion chamber of the stove or fur.-

nacein which it is usedso that all of the air which reaches the burner shall pass up through the legs of the arch and downgar-c113; through the discharge opening 7 t ereo..

p In practice a small quantity of oil will be poured onto the saucer shaped base of the gcueratorand ignited-'toraise the cone to vaporizing" temperature 'and'also heat the arch so that the air which passes up through the smnc and downward toward the genera- (or shall be heated. As soon as the generator is heated to the required degree, oil is peri and as it rises therein and in the narrow annular or circular space surrounding the stem of the spreader it is vaporized and the" vapor passes pp through the cone and between the lugs l7 and radially outwancl through the jet'drifices 13 where it mixes with the heated air from the air-draft arch 'andis lns'tantly converted into a combustible mitted to flow through pipe 12 into chamber gas which burns fiercely and with no visible smoke or soot, the flame and heat maintaining the generator at vaporizing temperature and the arch at a temperature which will insure the supply of heated an" to theburnering a plurality of openings, a

. erator supported by that the flame shall impinge the cone and base as well as draft tube.

said openings and as long as the same is in operation. The flame is extinguished by simply closingthe valve, not shown, controlling the passage of oil to the supply pipe 12. It will be noted that the spreader being conical willicause theair descendingupon it to travel downwardly and outwardly in all directions so directly .upon the legs of the Fromthe above description it will be apparent that we have produced a burner possessing-the features of advantage enumerated as desirable in the'statement of invention and we-wish it to be understood that we reserve the right to make such changes as properly fall within the spirit and scope I of the invention as defined by the appended claims.

We claim: 1. A burner, comprisi g a base plate havdraft tube its lower end with one of v adapted to discharge air downward toward the other opening,'a genthe plate and closing the opening last referred to and provided with a central chamber andupstanding hollow cone communicating at its lowerend' communicating at with said chamber, and provided at its" ing a plurality of openings,a' dra five cents each, by addressing Washington, D. 0.

upper end j with radial notches, and o a conical spreader-resting on the upper end of the cone and adapted for deflecting air discharged upon it by dially outward and downward.

2. A burner, comprising a base plate'havft tube communicating at its lower end with one of said openings and adapted to discharge air downward toward the other opening, a generator supportedbythe'plate and closing the opening last referred to and'provided with a central chamber and an upstanding hollow cone communicating! at its lower end with said chamber, and provided at'its upper end with radial notches, and a conical spreader resting on the upper end of the cone and adapted for, deflecting air discharged upon it by the draft tube, radially outward and downward, and provided with a cylindrical stem depending into the cone and with lugs for centering said stem'within the cone.' In testimony whereof we aflix our signatures, in the presence of two witnesses.
